Its structure is typically made of copper wire or other conductive materials, possessing good conductivity and mechanical strength, and capable of withstanding high voltage and high current operating environments. In practical applications, coils are not only used to generate magnetic fields but are also frequently used in transformers, motors, inductors, and other equipment, making them an indispensable key component in modern electrical systems.

[0003] The heat-insulated and anti-interference electromagnetic heating coil assembly is an electromagnetic heating device that improves heating efficiency and equipment stability by optimizing the coil structure and introducing heat-insulating materials. Its core lies in utilizing multi-layer coil windings and magnetic strip layout to enhance magnetic field concentration, while using materials such as silicone sheets and heat insulation boards to reduce heat radiation, protect the coil, and extend its service life. Furthermore, the assembly employs heat-insulating designs, such as upper and lower heat-insulating sheet structures, to reduce operating temperature and improve overall reliability.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-4This utility model provides an embodiment of a heat-insulating and anti-interference electromagnetic heating coil assembly, including a bracket 8. The bracket 8 is made of engineering high-temperature plastic through injection molding, possessing good high-temperature resistance and structural stability, providing a stable support foundation for the entire assembly. A protective component is installed at the bottom of the bracket 8, which is one of the core structures for achieving anti-electromagnetic interference and structural stability. A coil 6 is installed at the top of the bracket 8. The coil 6 is made by winding multiple strands of enameled wire into a bundle, with the twist pitch strictly controlled. This design ensures the conductivity of the coil 6 and optimizes the magnetic field distribution to a certain extent. An external wire 1 is electrically connected to the coil 6, which is used to connect to an external power source to supply power to the coil 6 to generate an alternating magnetic field. A heat-reducing component is installed at the top of the bracket 8, which is mainly used to block heat transfer and reduce energy consumption. The protective component includes an aluminum alloy plate 7. The aluminum alloy plate 7 has excellent electrical conductivity, which enables it to generate eddy current effects on the magnetic field leaking downwards from the coil 6. Through the interaction between the eddy current magnetic field and the leaking magnetic field, the leaking magnetic field can be effectively attenuated, thereby avoiding magnetic field interference with the bottom electronic components. This solves the problem of signal distortion and reduced control accuracy of the bottom electronic components caused by the leakage magnetic field in traditional electromagnetic coils. The aluminum alloy plate 7 is installed at the bottom of the bracket 8, and a fixing block 12 is fixedly connected to the bottom of the bracket 8. The fixing block 12 is made of plastic and is fixed to the aluminum alloy plate 7 by hot-melt integral molding. This connection method replaces the traditional buckle or screw connection. Compared with the traditional connection method, this method avoids the risk of mechanical loosening, greatly improves the reliability of assembly, and ensures that the aluminum alloy plate 7 can be stably installed at the bottom of the bracket 8 for a long time and continuously play a protective role.

[0032] Reference Figure 1 , Figure 2 and Figure 5The energy-saving components include heat insulation cotton 5, which is installed on the top of the bracket 8. Made of high-temperature resistant material, it has excellent heat insulation performance, effectively preventing heat from the cookware from being transferred downwards to the coil 6. A mica sheet 3, also made of high-temperature resistant material, is installed on top of the heat insulation cotton 5. This sheet not only further blocks heat but also evenly diffuses residual heat and provides good insulation, protecting the coil 6 below. A limiting block 4 is fixedly connected to the outside of the bracket 8, with the mica sheet 3 interlocking with it. This interlocking structure accurately positions and securely fixes the mica sheet 3, preventing displacement due to vibration or other factors during component operation and ensuring the stability of the heat insulation and insulation effects. Several partitions 9 are fixedly connected to the top of the bracket 8, with the coil 6 located between them. The partitions 9 regulate the winding trajectory of the coil 6, preventing loosening or deformation during long-term use. They also reduce mutual interference between different parts of the coil 6, optimize the uniformity of the magnetic field distribution, and improve the performance of traditional... To address the issue of poor magnetic field uniformity caused by a single magnetic strip arrangement, a mounting block 2 is fixedly connected to the outside of the bracket 8. The mounting block 2 supports and secures the wire 1, preventing damage from friction with other components due to movement, thus ensuring the safety and reliability of the circuit connection. The wire 1 is located outside the mounting block 2. A concave magnetic strip 10 is installed on the top of the aluminum alloy plate 7, and a concave groove 13 is formed at the bottom of the bracket 8. The concave magnetic strip 10 is located inside the concave groove 13. A strip magnetic strip 11 is installed on the top of the aluminum alloy plate 7, and a... There is a strip groove 14, and a strip magnetic strip 11 is located inside the strip groove 14. The magnetic strip is made of manganese zinc ferrite and is sintered at high temperature. It has good magnetic conductivity. The combination arrangement of concave magnetic strip 10 and strip magnetic strip 11 can further optimize the magnetic field distribution, enhance the uniformity of the magnetic field, and improve the heating efficiency compared with the traditional single magnetic strip arrangement. The concave groove 13 and the strip groove 14 can accurately position and fix the concave magnetic strip 10 and the strip magnetic strip 11 respectively, prevent the magnetic strip from shifting, and ensure the stability of the magnetic conductivity.

[0033] Working principle: First, when the equipment is in use, the coil 6 is energized by the wire 1 to generate an alternating magnetic field, thereby generating eddy energy and converting it into heat energy. Because the aluminum alloy plate 7 is made of aluminum alloy, the conductive properties of aluminum alloy are used to generate an eddy current effect on the downward leakage magnetic field of the coil. Through the interaction between the eddy current magnetic field and the leakage magnetic field, the leakage magnetic field is attenuated, avoiding magnetic field interference with the bottom electronic components and preventing signal distortion. At the same time, the bracket 8 and the aluminum alloy plate 7 are fixed by the melting fixing block 12 to prevent the equipment from accidentally disconnecting and causing safety hazards.

[0034] Secondly, during the use of the equipment, by installing heat insulation cotton 5 above the coil 6, the heat from the pot can be blocked from being transferred downwards. A layer of mica sheet 3 is then installed above the heat insulation cotton 5, which can evenly dissipate residual heat and provide insulation protection. Compared with the traditional coil, which has increased resistance and power consumption due to excessive temperature, this reduces ineffective power consumption. At the same time, the limiting block 4 installed on the top of the bracket 8 allows the mica sheet 3 to be installed quickly and not shift during use.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
